Abstract:
Seismic data acquisition and quality are affected considerably by the rugged terrain and complex geology of the Cordilleran thrust belt. With conventional CDP gathers and batch processing, it is surprising that we get interpretable data in some areas. Other problems affecting data interpretability are velocity pull-ups and migration. Velocities can produce antiforms on seismic data that appear to have thousands of feet of closure, while migration is critically important in recreating the subsurface geologic picture.
Seismic sections across the major producing trends of the Central thrust belt illustrate the structural forms of producing fields. It is noted that the structural style is similar in other areas of the Cordilleran thrust belt.
